All three have clearly stated goals on the front page. That was probably a course requirement. KeepVermontersWarm.com (which should probably be titled "Keep Vermonters Warm") has a .com address and an interesting design, which, it turns out, doesn't work very well. They've only managed two posts beyond the front page.

UVM Barf and Burlington Noise are using Blogspot. UVM Barf makes good use of the sidebar, but should adjust preferences to show more posts on the front page. They've post-dated a post stating the site's goal in order to keep it at the top of the page - crude but effective.
